Application led October 3, 1921. Serial No. 505,062; y

To all whom it may concer/rb:

,Be it known that I, ERNEST KoR'rnN, a citizen of the United States, residing at Sunbury, in the county of Northumberland and State of Pennsylvania, have invented certain new' and useful Improvements in Bunch Builders, of which the following is a specification, reference being'had therein to the accompanying drawings. 1

This invention relates to bunch builders, and .the object of the., invention is the -provision of means for automatically controlling the width and depth of the bunch made on the winding spindle, or bobbin, by` the bunch builder. l, i

. One of the essential operations in automatic 4wea-ving consists in replacing exhausted bobbins by full ones. This operation must I tion.

be accomplished `while the loom is running, and without introducing any imperfections .inthecloth It is'accomplished by a. train of mechanism-which functions and starts i with the-feeler of the loom. Various types have vantageous and will, therefore, confine my descriptionto this one type. f Y

` When the bobbin vhas been exhausted, the feeler slides along the bare wood ofthe exhausted bobbin. `This sliding motion is transmitted and sets'into operation the re- Vplenishing mechanism. One orl two revolutions of the loom may be required for this mechanism tocompletethe workfof replacing the exhausted bobb'in by afresh one. Durin .the revolutions filling must be supplied or the cloth. But since theoperaof the feeler depends upon its. sliding along the bare wood of the bobbin, itis obvious that the filling required vfor the extra revolutions cannot be 'storedfon ytheV same part ofthe bobbinas that used for the/main supply ofthe thread. For, if any fill-ing were on the-quill in front of the feeler, this 'part could noty slide along the wood, and

Set ino Opration'the'vreplenishing mechanism.y "11. f i

, v"The extra' therefore be vstored in' aV small bunch at the base Aof the bobbin out offreach lof the feeler. Further, the yarn in this small bunch must be 'a continuation l'of''theyarn ofthe bobbin'proper. Again, the -bunch must be wound tightly, otherwise vlaye-rs' yofzthe yarn 4fromjthe bunch would `fall'or slide down, rbecome ent-angled with the yarn of the bobbin proper and iin-allyA be i carried' into the oods v`to form weaving 4imperfections, besi es prohibiting `proper operation of the feeler. It is the object of this invention to insure the winding of the bunch tightlyl and ,-in

such a fashion that it will not fall down or become 'entangled during any operation through which the iilling carrier is' put. 3

A further object is the provision of means for automatically controlling the width `and depths of the bunch made on the winding spindle or bobbin by the bunch builder.` .With the foregoing and other objects in view, my invention comprisescertain novel combinations, constructions andrfl arrangements of parts as will be hereinafter described, illustrated in the accompanying v drawings, and more particularly pointed` out in the appendedclaims.` y

A bolt 10 pivotallykconnectsgthe =lever and broadened portion' 11 of the lcontroller arm 5. Slots 3,4 and. 9register (Fig. 2) 'and in these slots is bolt12 fory fasteningll'ever v6, controller arm=5 and threadguide 1 to'- gether, buty permitting the levery 6- to s'win upon itspivot, constituted byvholt10,an

impart a lreciprocating, movement the y 0n' the traverse bar 131 is a, block 14, which o'fblockll,'andl .they lock screw- 16 is, threaded into the bottom of block 14, with its inner end in the annular groove 16a',v on the collar-member 15a. The lever 6 has its portion 7 slidably mounted in the transverse' aperture a of the collar-member 15a; this l'ever 'is-, therefore, mounted to slide freely 1n the collar-member 15a, carried by block 14.

The operation of the device is as follows: The bobbin 17 is first placed on the Winding spindle 18. The thread guide 1 is then movedjinto 'position in the same manner as heretofore in the case ofthe regular bunch builder. The yarn is then passed through guide 1 on the bunch builder, and then to the thread' guide 19 on the traverse bar 13. After the machine has been started, the traverse bar 13, which is known yto have a `reciprocatingmotion,imparts the same motion to the lever 6'. The lever 6, which, as previously explained, pivots` uponlbolt 10, and being engaged by bolt 12 in turn impart-san identical', lyet lesser, `predetermined motion to the thread guide 1. This motionv causes the yarn to travel back and forth on the bobbin 17, thus makingk a bunch of' a certain depth. As soon as the thread guide 1 is released throughy the operation of the mechanism within the bunch builder 20, the rounded body 7, of the lever 6, glides along the collar 15?, yet, remainingr in contact with vthe same. VVhen the yarn has been auto matically released from the thread guide 1 on the bunch builder 20, it is then fed from the thread guide 19 on the traverse bar 13 and-is thus traversedfduring they remainder of the winding of the yarn, which constitutes vthe bobbin: proper. Y `The bunch builder 20 is lusually constructed in various types. I use, in conjunctiony with my improved device, a type such i asl hereinbefore specied, und'erfthe patents listed; The machines manufacturedunder the. designated. patents are generally known as Universal winders. y

'The operation of quill-winding for my devvice consists of two4 parts.y First, the small bunch is wound on the base of the bobbin,

Y .then the'yarn. of the bobbin proper is wound onf the. remainder. I am concerned only with `theiirsf part ofthe operation, that of con- `strilicting'the bunch.` l

I'A-sn.hert-iinbefore stated, the bobbin 17` is first placed von the spindle 18: The thread guide '1'l is: placed in position by `placing it to the left'when it will catch, in the bunch .ubuilder 20, with afclick. Then the yarn is threaded ythrough thread guide `19,`located von the traverse bar 13, then through' the eye of the` thread guide 1 of the bunch builder k20, whereupon, the machinery is'started,

Y scope yof` the appended claims.

causing the revolution ofithe.bobbin and also causing the traverse `bar to be moved forward and backward. In its motion, the traverse bar is constantly in contact withvthe small lever 21, at thewleft '.Ofthembuiich builder 20, hence,'p`res'sesmthis small lever backward. A spring (not shown) on the inside of the bunch builder 2O keeps it in contacty with the end of the traverse bar 13.

After the small lever 21 has been pushed backward a number of' times, it is :automatically drawn to the right andaway 'from contact with thev traverse bar 1,3.4 In 'the samemovement, the threadv guide 1 is 'also drawn to the right, due to' the action of the spring (not sho-wn) on the inside ofthe bunch builder. In movingA to the right, ithe thread guide 1 becomesi unthreaded,afnd the yarn now passes directly through the thread guide 19 of the traverse bar 131and is. traversed back and, forth, forming. the bobbin proper. ,f .l 'M

During the interval that the'thread'is held stationary: at thebase of the bobbin, through the agency of the thread guide 1, a small,' loosely wound bunch will be formed bythe rapid revolution of the bobbin. With my improved device, theoperation of which has been hereinbefore specificallyy explained, during this same interval, the yarn is not held stationary, but is traversed lback and. forth on the base ofthe bobbin due to theslidi'ng movement imparted to the thread 'guide '1 by the lever 6 and so forms a tightly'wou'nd bunch. This advantage is accomplished hy-` having the thread guide '1 movable traversed back and. forth by the lever 6 to which is imparted a reciprocating motion bythe traverse bar 13. 1
